Welcome to NGA, SanDiegoan!
I wonder if you can mostly avoid touching foliage, until you get your harvest? Can someone else help with "touching" chores?
I've also found that allergies seem to be cumulative for me.
I lived in a moldy basement for a while, and it didn't bother me noticeably.
I had a cat, and the cat didn't and doesn't cause any allergic symptoms that I notice.
But, together, they gave me congestion and sandy eyes.
And now, on a high-pollen day, I may wake up with allergy symptoms in my cat-saturated home.
But I know that the allergy will go away once I get out of the house.
And on low-pollen days, the house does not cause any allergy symptoms.
Say, do you have any neighbors with tomato plants, that are NOT San Marzanos? If you're willing to give yourself more symptoms "for science", you might be able to figure out whether it is just SOME varieties of tomato plants, or all of them.
